Audio input level is too high. Reduce so most stations are around 50.

Thanks for the heads up.
For X-Cubesat the GMSK transmitter is chosed by default on the scheduling page and by the auto-scheduler, as this has most ‘good’ observations. This likely is due to users seeing signals and vetting the observation as good, even when the transmitted signals are AFSK. @fredy has disabled the GMSK transmitter for now so we can build up some stats on the AFSK transmitter, hopefully with many decodes.
Just aiming for more and more decodes
Good work you guys.
Hi all,
Student’s Centre Spatial X-Cubesat ground station in Polytechnique school is asking the satellite radioamateur community to send telemetry reports of X-Cubesat as it is going to decay soon and finish its life by burning into high Earth atmosphere. X-Cubesat team is interested by telemetry frames sent during final livfe phase of the cubesat.
Thanks for sending tlm reports.
